Inphi Corporation announced that load-reduced dual-inline memory modules (LRDIMMs), enabled by Inphi’s iMB, have been fully validated and supported on the new AMD Opteron 6200 Series processors, formerly code-named “Interlagos.” The validation provides memory vendors and systems designers the assurance that they can populate AMD Opteron 6200 Series-based systems with up to 768GB of cost-effective memory for today’s demanding enterprise and cloud-based applications in 2P servers.

The Inphi iMBGS02A passed several rigorous validation tests by AMD across process, voltage temperature and frequency. Now shipping in volume and fully compliant with the memory-buffer specification of the JEDEC Solid State Technology Association, the devices have now been verified for compliance on the AMD Opteron 6200 Series platform, for devices’ interoperability.

“Today’s servers are called upon to handle an ever-increasing array of tasks, but in smaller spaces, demanding less energy and at lower overall costs,” said Pat Patla, Corporate Vice President for AMD’s Server Business. “With solutions such as Inphi’s iMBGS02A that are now fully validated on the AMD Opteron 6200 Series platform, those servers can achieve their space, energy and cost objectives.”

“With the AMD Opteron 6200 Series, AMD has created a tremendous platform for the next generation of powerful yet cost-efficient servers, for which LRDIMM technology provides the ideal memory-management solution,” said Paul Washkewicz, Vice President of Marketing, Computing and Storage at Inphi. “The validation Inphi has achieved through AMD provides the market with assurance that fully populated, high-speed LRDIMM memory modules will operate optimally on the AMD Opteron 6200 Series platform.”

LRDIMM Technology: Capacity, Scalability, Speed

Unlike traditional registered DIMMs, or RDIMMS, which limit the amount of server memory that can be installed due to their loading profile, LRDIMMs replace the register with an isolation memory buffer to reduce the load. This enables servers’ memory to be easily scaled upward, with more and higher-density DRAMs on each module, so that both capacity and speed are boosted while using the same motherboard real estate as an RDIMM.

AMD Opteron 6200 Series processors have been architected to provide optimal performance, scalability for virtualization and higher efficiency in cloud computing. The memory bandwidth and scalability of the AMD Opteron 6200 Series processor is ideal for virtualization as it enables up to 73 percent more memory bandwidthi, helping servers to host more virtual machines.
